From what I've seen this year, I don't think I'm that worried about good press covereage from UVA. So far it seems that when the backers and safeties get out of positon, BYU is able to move pretty well, and if the CB's are in press, they can't see the play developing to help.
Basically, if the dline can get pressure on Hill and the backers can stay home and the safeties can help with coverage rather than fill for lost backers, BYU could be in trouble.
This is why I really hope Algie Brown is back. He's a nightmare coming out of the backfield and opens up lots of other stuff.
